A dedicated Business Analyst
We set up a Business Analyst (BA) dedicated to the model and fed by the reports. The model always remains accessible to the client. Finally, after each workshop validation, the BA will configure the application that will be presented during the following workshops.
This organization allows us to rely on target customer screens, even if they change during the analysis phase. This iterative method continues after the workshops, during the configuration phase.
Regular meetings allow us to present the progress of the solution to the teams. The tunnel effect is thus non-existent and the schedule is secured.
